Answer to Question #72938 in Physics for Zeinab Toufaily

Question

Olalliberries at 85% moisture and at room temperature (25C) need to be heated to boiling and maintained there for 30 min. Your batch size is 50 kgs. You can utilize steam at 198.5414 Kp. Assume boiling for the Olalliberries is 100C. The condensate exit temperature is 100C. The berries will need 5000 J/kg.hr to keep them at boiling.

How many kilograms of steam will be needed to accomplish everything?
Use same characteristics of steam of Question 6 at 115 o C .
Cp = 3.44 Kj/Kg °C
25oC {█(Hc=100.7KJ/Kg@Hv=254.4KJ/Kg)┤
